hi,

iam using a timer in my appplication with jbpm4.3 with spring 2.5.

   <state name="waitForNotification">
        <transition name="go on" to="notificationStatusSuccess"/>
        <transition name="timeout" to="Timedout">
            <timer duedate="30 seconds"/> 
        </transition>
    </state>

in my web.xml i have given setvlet

<servlet>
         <servlet-name>JobExecutorServlet</servlet-name>
         <servlet-class>org.jbpm.job.executor.JobExecutorServlet</servlet-class>
         <load-on-startup>3</load-on-startup>
     </servlet>
     
     <servlet-mapping>
         <servlet-name>JobExecutorServlet</servlet-name>
         <url-pattern>/jobexecutor</url-pattern>
     </servlet-mapping>

The jbpm version is 4.3. The jbpm dependencies are

<dependency>
        <groupId>javax.annotation</groupId>
        <artifactId>jsr250-api</artifactId>
        <version>1.0</version>
    </dependency>
    <dependency>
        <groupId>org.jbpm.jbpm4</groupId>
        <artifactId>jbpm-test-base</artifactId>
        <version>${jbpm.version}</version>
    </dependency>
    <dependency>
        <groupId>org.jbpm.jbpm4</groupId>
    <artifactId>jbpm-jpdl</artifactId>
        <version>${jbpm.version}</version>
    </dependency>
    <dependency>
        <groupId>org.jbpm.jbpm4</groupId>
        <artifactId>jbpm-pvm</artifactId>
        <version>${jbpm.version}</version>
    </dependency>

While runnig the application using jetty server it is giving the error given below and also the timer is not fired.

ERROR: org.jbpm.db.JobSession - org.hibernate.MappingException: Named query not known: JobSession.getFirstAcquirableJob
ERROR: org.jbpm.job.executor.JobExecutorThread - exception in job executor thread. waiting 5000 milliseconds
